Stephen Kelly 89ba7b0046 Update the Clang pattern to specify compiler options.
In Clang 3.4, the preferred (and new) option pattern is --target=.

 http://thread.gmane.org/gmane.comp.compilers.clang.devel/29975
 http://llvm.org/viewvc/llvm-project?view=revision&revision=184408

Clang 3.4 is not yet released, but there is a release candidate, and
there is a dashboard test of Clang trunk.

Stephen Kelly 7cd65c97fa Add CMAKE_SYSROOT variable to set --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Stephen Kelly 5096967ecd Allow toolchain files to specify an external toolchain.
Clang can compile code, but uses the gcc tools for other tasks such
as linking. The -gcc-toolchain option can be used for that, but
generalize so that other compilers can be treated the same.

If such a location is specified, use it as a hint for finding
the binutils executables.

Stephen Kelly 76552d595d Add compiler target compile options.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like

 set(triple arm-linux-gnueabihf)
 set(CMAKE_C_COMPILER "/usr/bin/clang")
 set(CMAKE_C_COMPILER_TARGET ${triple})
 set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
 set(CMAKE_CXX_COMPILER_TARGET ${triple})

or

 set(arch gcc_ntoarmv7le)
 set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
 set(CMAKE_C_COMPILER_TARGET ${arch})
 set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
 set(CMAKE_CXX_COMPILER_TARGET ${arch})

Both clang and qcc are inherently cross compiler( driver)s.

When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET
as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils.

When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET
to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.

Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.

Brad King 3d8356d486 Clang: Support Windows variants for GNU and MSVC (#13035, #14458)
Teach the compiler identification preprocessor tests to report when
Clang simulates MSVC, and what version.  If not MSVC, assume GNU.

Teach compiler information modules Clang-(C|CXX) to recognize when Clang
simulates MSVC and skip loading the GNU information.

Teach the Windows-MSVC platform information to recognize when it is
loaded as the simulated compiler and use that version information
instead of the real compiler's (different) version scheme.

Add platform modules Windows-Clang-(C|CXX) and support module
Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap
the corresponding information macros.

Store in new platform variables

  CMAKE_${lang}_COMPILE_OPTIONS_PIC
  CMAKE_${lang}_COMPILE_OPTIONS_PIE

flags for position independent code generation.

In almost all cases, this means duplication of the
CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
assumed pie equivalent for the _PIE case.  Note that the GNU compiler
has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
Windows or Cygwin.

There is a possibility that the _PIE variables are not correct.
However, as there is no backwards compatibility to be concerned about
(as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
the current state suffices.

Modestas Vainius e1409ac59b Support building shared libraries or modules without soname (#13155)
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it.  This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.

Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question.  Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it.  Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded.  Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well.  Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.

The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders.  Final substitution is
performed by ninja at build time.  Therefore we cannot conditionally
replace the soname placeholders on a per-target basis.  Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME.  Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.

Brad King d468a2c2cb XL: Avoid copying archives into shared libraries that link them
The XL toolchain supports shared object files stored in archives.  Since
CMake lists libraries on link lines by full path it is common for a
shared library link line to contain the path to an archive file.

When linking a shared library the compiler front-end by default runs
CreateExportList to construct the list of symbols to be exported.
Unfortunately it passes all files found on the command line to the tool
so archive and library files get processed along with the object files.
The tool returns a list of all symbols in all objects, archives, and
libraries on the command line.  This causes the linker to copy every
object file out of every archive into the shared library whether they
are dependencies of the original object files or not.

Work around this problem by running CreateExportList ourselves with just
the original object files intended for inclusion in the shared library.
Then pass the list it produces on the link line to prevent the compiler
front-end from constructing its own.  This tells the linker to export
only the symbols provided by the original source files of the shared
library.

This commit changes the way how the assembler support works in cmake.
The language "ASM" now always uses the C/Cxx compiler instead
of the assembler directly. This fixes #8392, assembler files are
not preprocessed.
If one wants to use the assembler directly, the specific
assembler "dialect" has to be enabled. I.e. to get as/gas,
you have to use now ASM-ATT, the same way for ASM_MASM and ASM_NASM.

Implemented this now for gcc.

Brad King c106cb2e2f Generalize support for Portland Group Compiler
We factor flags from Platform/Linux-PGI-Fortran.cmake into language
independent helper modules

  Compiler/PGI.cmake
  Platform/Linux-PGI.cmake

and invoke the macros from

  Compiler/PGI-<lang>.cmake
  Platform/Linux-PGI-<lang>.cmake

This enables general support for the PGI compilers.

Brad King e28c16b482 Split GNU compiler information files
This moves GNU compiler flags into new-style modules

  Compiler/GNU-<lang>.cmake
  Platform/<os>-GNU-<lang>.cmake

We use language-independent helper modules

  Compiler/GNU.cmake
  Platform/<os>-GNU.cmake

to define macros consolidating the information.

Brad King 1f06c33f8e Drop -rdynamic from Linux build rules
This is a GNU-specific option that should not be specified for all
compilers on Linux.  It tells the GNU compiler to pass -export-dynamic
to the linker to export symbols from executables for use by plugins.
Since we provide the ENABLE_EXPORTS target property to do the same thing
in a cross-platform way, there is no need to pass -rdynamic always.

Since the option is not useful for GNU tools and breaks other tools on
Linux we simply remove it from CMAKE_SHARED_LIBRARY_LINK_<lang>_FLAGS.
This also allows us to stop setting the variable in other Linux compiler
files just to erase the bad flag.

See issue #9985.

Brad King 83816cc6ec Add support for the g95 Fortran compiler
This commit teaches CMake about the g95 compiler from

  http://www.g95.org

We use 'G95' as the compiler id string, and add some basic flags.

See issue #9241.

Brad King e1729238c9 Add initial XL C compiler flags for safer builds
This commit adds some default initial C flags for the XL compiler.  The
most important is "-qhalt=e" which causes the compiler to error-out on
non-severe error messages.  This is necessary to get try-compiles to
fail when bad arguments are passed to a function.

Brad King 6d434ee6cc Split XL compiler information files
This moves platform-independent XL compiler flags into separate
"Compiler/XL-<lang>.cmake" modules.  Platform-specific flags go in
"Platform/<os>-XL-<lang>.cmake" modules.

Brad King 2eca4dd2d1 Use Intel for Linux flags only on Linux
The commit "Split Intel compiler information files" moved some Linux
specific flags into the platform-independent Intel compiler info files.
This moves them back.

Brad King 115ecc5750 Teach compiler id about VisualAge -> XL rebranding
IBM rebranded its VisualAge compiler to XL starting at version 8.0.  We
use the compiler id "XL" for newer versions and "VisualAge" for older
versions.  We now also recognize the "z/OS" compiler, which is distinct
from XL.

Brad King 34c6588b6e Move flag to Compiler/VisualAge-Fortran module
The CMAKE_Fortran_DEFINE_FLAG value applies to the IBM Fortran compilers
on all platforms.  This moves the setting to the platform-independent
compiler information file.

Brad King 35f36727c5 Set CMAKE_<LANG>_VERBOSE_FLAG variables for PGI
We set the variables to contain "-v", the verbose front-end output
option for PGI compilers.  This enables detection of implicit link
libraries and directories for these compilers.

Brad King 07ea19ad1f ENH: Implicit link info for C, CXX, and Fortran
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers.  We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends.  We store results in new variables called

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES

The implicit libraries can contain linker flags as well as library
names.
